How is a biological population different from the population of a whole ecosystem, such as a rainforest?

Describe what needs to occur in order for a metamorphic rock to form.

katovenus [111]

Answer:

Any sort of prexisting rock whether sedimentary, igneous, or even metamorphic rock must change under extreme conditions like extreme heat or pressure.

Explanation:

An igneous rock is a rock that has been created via cooling of magma.

A sedimentary rock is formed from sediments, whether they be natural like seashells, or other pieces of older rocks that have worn away. usually formed under pressure.

A metamorphic rock is a rock that's changed, because it was put under extreme pressure or exposed to extreme heat.

Think of the part morphic in the word metamorphic-it literally means that it morphed or that it changed dramatically.

There are two ways for a rock to become metamorphic under extreme pressure or extreme heat. and there are two types of metamorphic rocks, contact metamorphism and regional metamorphism.

Those mean pretty much exactly what they say.

If you have any more questions, ask, but i think I covered the most important parts of the answer.

best of luck

Match the following terms and definitions. 1. an electrical nerve impulse sent by nerve fibers to the central nervous system for

vladimir1956 [14]

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. Action potential.

2. neurons that detect chemicals such as those found in food. Chemoreceptors.

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. Compound eyes.

4. the structure that gives the response to an environmental change. Effector

5. neurons that detect electrical fields. Electroreceptors.

6. secretion of hormones into the blood stream to affect distant processes. Endocrine.

Explanation:

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

Some of the food in the protein group and dairy group are high in saturated fats and cholesterol. These raise which cholesterol

BigorU [14]

The food in the protein group and dairy group are high in saturated fats and cholesterol, it raise LDL in blood.

<h3>What is cholesterol?</h3>

Cholesterol is a waxy like substance synthesized from two sources such as liver and from animals like meat, poultry, diary product.

There are two types of cholesterol, one is bad called LDL cholesterol and second one is good called as HDL.

LDL narrow down the arteries by depositing fats in it, the condition known as atherosclerosis which leads to increase in risk for heart attack, stroke and peripheral artery disease.

On the other hand, HDL protect against heart attack and stroke

Third component called triglycerides are the common type of fat act as a reservoir of excess energy.

Hence, LDL is the correct answer.
